A few honorable mentions:
The Cyberwire - Daily Cybersecurity News. Very timely and informative. They recently added a new CSO Perspectives segment that will be useful to you.
Recorded Future - Great podcast that contains more business-oriented Cybersecurity news and interviews than some of the others.
Hacking Humans - Weekly Cybersecurity News, from the same people who do the Cyberwire, focus on social engineering attacks.
SANS Internet Stormcenter Daily Stormcast - GREAT 5 minute podcast released daily. High level, quick coverage, but doesn't have the story telling or detail that I usually prefer.
Darknet Diaries - Narrative-based podcasts that spend a single or a few episodes to tell the stories about some of the most important or interesting hacks throughout history. Probably not as "useful" as some of the others, but very interesting storytelling.
Malicious Life - Like, Darknet Diaries, this is a narrative-based podcasts that spend a single or a few episodes to tell the stories about some of the most important or interesting hacks throughout history. Again, probably not as "useful" as some of the others, but very interesting storytelling.
Cyber Motherboard - Weekly Cybersecurity News and stories from Vice - has some cultural/political leanings, but covers very interesting stories.
